Transformation of Goguryeo to Majin

In 904 CE, the state of Later Goguryeo underwent a formal transformation when its ruler, Gung Ye, renamed the kingdom Majin, marking a shift in identity during the Later Three Kingdoms period of Korean history. This change occurred against the backdrop of the decline of Unified Silla, when regional leaders established rival states across the Korean Peninsula. Gung Ye, a former Buddhist monk, had founded Later Goguryeo in 901, presenting it as a successor to the earlier Goguryeo kingdom. By 904, he introduced the name Majin, signaling a move away from a purely revivalist identity. The renaming reflected his effort to consolidate authority and establish a distinct political structure under his leadership. In the following year, 905, Gung Ye relocated the capital to Cheorwon, strengthening his control over central territories. During the Majin period, Gung Ye’s rule became increasingly centered on religious claims. Historical records describe how he declared himself the Maitreya Buddha, a future figure in Buddhist belief, and asserted supernatural abilities such as reading minds. These claims were used to justify strict control, including the execution of individuals he perceived as disloyal. Over time, such actions contributed to growing dissatisfaction among his followers and officials. The transformation from Later Goguryeo to Majin was part of a broader period of political fragmentation and experimentation with authority. Gung Ye’s rule continued until 918, when he was overthrown by his generals, leading to the rise of Wang Geon and the establishment of the Goryeo Dynasty.
